Exception in LiveAuxiliaryDataSynchronizingEnumerator

Actual Behavior

I am facing an exception on LiveAuxiliaryDataSynchronizingEnumerator.cs

2023-01-25 11:10:00 Runtime Error: Instant out of range for DateTime in LiveAuxiliaryDataSynchronizingEnumerator.cs:line 179

Expected Behavior

I have tried debugging the LiveAuxiliaryDataSynchronizingEnumerator.cs at line 179. It is trying to convert the EndTime to UTC. EndTime was already matching with the UTC. I am in India which is GMT+5:30 (TimeZones.Kolkata). I am not sure what the actual behavior but the aforementioned behavior is incorrect.
Also, all subscribed symbols are unsubscribed on the first tick.

Hi @Amol-Gupta!
Thanks for the report. Lean expects data to be emitted in exchange time zone as per the market-hours-database specifications.

It is trying to convert the EndTime to UTC. EndTime was already matching with the UTC.

That sounds like the bug, ref https://github.com/QuantConnect/Lean.Brokerages.Samco/blob/master/QuantConnect.SamcoBrokerage/SamcoBrokerage.cs#L838
